The said ducts or pipes 9 may be provided with a window 10,

,of glass or other transparent material, to.90

enable the attendant to observe the flow of and to gage the quantity of pulverized cork necessary to be fed into the-hopper 7 and conveyer 8.

Arranged upon a platform 12, -or other suitable place, are suitably constructed solution-containing heaters and mixers 11, which are provided with spouts 13 for conveying or guiding the solution from one or all of the said heaters or mixers v11`to the 100 hopper 7 and into the previously-mentioned conveyer 8 in which the cork-material and solution are thoroughly mixed and conveyed by means of'a rotating screw or worm,.as

13', which is also preferably provided with 105 baliles or arms, as 14, to a spout 14. The material, when it reaches this spout is sutii'- ciently mixed and sufficiently hardened, so

as to be formed into composition sheetboard, by means of that part of the mechanism or apparatus in which the compression takes place, and which part of the apparatus will hereinafter be termed the corkcompressor.

- This cork-compressor consists, essentially, of a main supportingframe 15 to which are suitably secured suitablel uprights or standards 16 which are made rigid by means of longitudinally extending brace-supports 17, transverse upper brace-supports 18, and

-lower brace-supports 19, all of which are l rigidly securedin their properly assembled relations, by means of bolts 20, or other suitably constructed fastening devices.

As shown,A cylindrical compression rolls 22, 23 and 24 fgre suitably mounted in horizontal bearings 25 and 26, said bearings,l and in consequence' thereof the said rolls, being capable of longitudinal adjustment,

such adjustment being adapted to be made -by means ofbolts 2'7vvhich pass through` elongated openings orslo'ts 28 formed in the` mainframe l15, allo'f which is clearly shown, and lthe bearings being preventedi from shifting by means of the said bolts, as Will be lclearly understood. A cylinder 21, similar in construction to and of the saine diameter as the cylinder 24, 'is also employed and serves as a take-.up roll for a suitable belt 29 which rides upon the said cylinder 2.1 and the cylinder 22. An upper set of cylindrical compressor rolls 31, 32, 33 4and..34 are suitably mounted and are free to revolve in vertical bearings, as 34, which are also t adjustable, but in vertical or vupright directionthrough the aid of elongated openings `or slots 30 in the'uprights or standards 16 y and suitable bolts 3 5, as Will'be 4clearly evident.

34,'is in the form of a tube or piece of piping, suitably secured to or connected at its ends to'v suitably .formed heads or spiders, as 35,`provided With outwardly extending tubular projections l36, 'forming theaxles of the said rolls, and by means of Which the said rolls are rotatably mounted in 'the respective bearings. Each journal-like tubular projection 36 is also formed with a ,re-

duced shank-like end-portion, as 37, the pur-l pose of vvhich will be hereinafter more. fully explained. The Apreviously mentioned takeup roll 21, and the roll 24 which serves as a guide-roll, as has been stated, are similar in construction, their cylindrical surface-portions being preferably made with sectional Woodbatter 38, which is screwed or glued to the headsor spiders 39 and 40 of the respective rolls 21 and 24, these heads or spiders being keyed to the steel shafts 41. Each shaft 41 is provided With the reduced free end-portions 42, the purpose of which horizontal mainframe 15. Upon the'saidA shaft 49 `is' keyed, or otherwisesuitably secured, va pinion 51 which meshes with an intermediate spur-gear 52,-jsaid spur-gear being provided at its center with a suitable stub-gear 53, both of Which are loosely and rotatably mountedupon a stud-pin, as 54,

extending from the side'of a yoke-like elei ment or member 55. The upper end-portion of this yoke-like element or member55 is loosely or pivotally suspended from the journal-like projection 36 herein-above men- The preferred construction of each'cylindrical compressor roll 22, 23, 31, 32, 33 and tion'ed, the said element or member 55 being alsoprovidedwith a slotted segmental portion 58, through the slot lof Which, which is concentric vwith the central axis of the projection 36,extends,a stud-bolt 57 which is-secured in the main frame 15 and is adapted for firmly fastening the said yoke-like element or member 5v5 in its properly adjusted relation. yThe purpose of this yokelike element or member 55 isfto change the spur-gear 52 to one of a smaller or larger diameter, when it is desired to change the.

speedof the compressiof,l rolls, the said element o r member 55 being 'swung in either direction, accor-ding to the size ofthe spurgear, so that the latter Will properly mesh with the pinion 51, after which the said ele- -ment or member 35 isl firmly clamped by means ofthe stud-bolt 57.*in its rigid po-4 sition, as will be clearly understoodi," j

spur-gear 52 is another spurfgear 59 which is securedupon the previously-mentioned' shank-like end-portion 37 of the tubular projection 36, the said gear 59 having in mesh therewith a pair of intermediate gears 60 .and 61 respectively mounted and secured upon a pair of revolving shafts 62 and The said intermediate gear 61 meshes with a spur-gear 64 which is keyed to the shaft...

41 of the compression or guidc-roll 24- for'l -g producing the rotary motion of the latter,

and the intermediate gear 60 in'turn meshes with an intermediate gear 66, which is loosely mounted upon al shaft or stud 67 fastened to an arm 63 which is supported at its one end loosely upon-the axle or journalportion ofthe compression roll 22. Suspended from a stationary shaft 7 (l isa supporting arm 69 with the lower end-portion of which the said stud 67 is oscillatorily connectedf` Bymeans of another intermeof compressionrolls and a pair of intermediately disposed shafts 77 and 78.

Directly beneath the belt 29, as will be more particularly seen from an inspection of Fig. 3 of the drawings, is an idler roll 79 Which is rotatably mounted in pillowblock bearings 80. suitably secured to and -supported upon the uprights or standards 16', andto the left of this idler roll 79 isa compression plate 81 which is suitably secured to vertical brackets 82`upon the main frame 15, preferably by being screwed to the said brackets. The said plate 81 andthe roll 79 i serve as a guiding meansfor the belt 29, said roll 79 with the roll 3 1 firmly compressing the composition cork-material as the iii-st compression occurs. The said plate 81 may `also' be properly adjusted and may be se-f lool -diate gear 70,'\vhich is loosely mounted upon i 'the said shaft 70, rotary motion is trans-I `mitted to a train of gears 71, 72, 73, 74,775, -and 76 all of which are respectively operatively connected with and to the upper set 85 In mesh with the stub-pinion 53 of the n""ucurely clamped orfixed in its adlstedpo' sition by means of suitableboltswhich enter elongated openings `or; slots in .the main frame 15. Prov' means of the previously .mentioned t up roll which is `supportedupongt the latter'- being, adjustable lengthwise/by meansA of an arrangement of jga'djusting screws, as 84 and 85,.which are threaded into the members :86 and 87, whichj'injflturn are secured upon the main frame Thesaid lower and upper compression. rolls 22,23,-t 32 and 33- are also suitably and gently heated by steam or gas, as may be preferred,to a;

,sufficient 4degree of heat, in order that the composition board is a trifle softened, so that 20..

the consecutively following compressions of the material are properly made and take y place, as the operationsproceed. The heating facilities, in the present instance, com- 5 prise within each compression roll a suitable arrangement of tubular gas-burners, as 88, which are located near the inner peripheral surfaces of the rolls, substantially as shown in Figs. -7 and 8, gas being admitted to the said burners 88 through an arrangement 4of' pipes 89,90, 91 and a main supply pipe 92, the pipes 90 .passing through the journallike` tubular projections 36 herein-before i mentioned. Thus it will be evident, that as sheet-board.

the compression rollsfrevolve, their peripheral surfacesare constantly kept heated. A suitably 'constructed regulator, as 93, is 'also provided to control the amount of air which enters` the`said compression-rolls through the openings in their heads 35, the regulator being easily adjusted, according to existing conditions, by means of an adjusting device 94, as a wing-nut and screw, see Fig. 3,'

the screws being disposed in concentric slots 95 and the wing-nuts being clamped upon Athe inner faces of the heads 35, as will be clearly evident Provision is furthermore made in the-forml of a flexible tube, as 96, which i's connected with the pipe 91, to give free admission to the gas at all times, as adjustments' are being made on the cylindrical compressors for gaging the thickness of the By means of suitable adjusting screws 97 which are fitted and work in correspondingly threaded portions of supporting 1 brackets 98, said. brackets being suitably mounted and secured upon the standards or uprights 16, the uppercompressor-cylinders can beelevated to a proper height so as to be accommodated to they composition which is to be compressed into .sheet-boards of various thicknesses. After `the proper .adjust-- ments have been made by means of these screws, the previously-mentioned vertical bearings 34" are permanently secured in A n isalso.n ia'de.to'takeup a l. ih@ Slack 0f the blt 29-"and is accor'npli'shedjj/ other necessaryQbearings, as 99,` whichA are ake-ff i; rights andserve as .supports forl the interllljnwhich is rotatably mounted iii-1 thebear-; ing-.portions of suitable pillov'v--block's283,1`

. ably formed Scrapers 100 are affixed to bars .101 which are fulcrumed in brackets102 and 103, the brackets 103 being stationar by being fixed to the uprights or standar s 16,

whereas the brackets 102 are adapted to be raised with the upper compressor-cylinders by being secured to the vertical bearings 34. Weighted arms, as 104, are also rigidly connected with thesaidjbars 101 whereby the scraping contact of the Scrapers with the compressor-cylinders is maintained, and the materia-l in passing between the cylinders is thereby prevented from adhering to the sur-- faces of the cylinders in case a more-or less stickyv solution is used for the various compositions made. Rotary cutters 105 mounted upon a splined shaft 106 are also used, said shaft being mounted in bearingbrackets 107 secured upon the standards or brackets 16, said cutters being employed for splitting the cork-material, if desired, into several narrow strips and to trim the marginal edges of the two outer strips, as .the cork-material travels through the machine.. `Suitably mounted upon the outer end-portion of said shaft 106 is a driven pulley 108, said end-portion of the said shaft being also rotatably mounted in a suitable bearingbracket 109. y Fig. 8, receives its rotary motion from a driving pulley 110 which 1s keyed to the The driven pulley 108, see.

main shaft 49, the end-portion of said shaft `49 being also rotatably mounted in a supporting bearing 111'.

To prevent the sheet-board from sagging and to properly guide the material as 1t 1s being carried from one set ofcylinders or rolls to the next set of cylinders or rolls,- suitable supporting lingers or plates 112 are mounted upon rods 113 and upon the bars 101, the said rods 113 being'icarried by suitably constructed members or elements 114 V which are bolted or otherwise secured to the said' uprights or standards 16. vThe -said lingers or plates 112 are also provided with suitably .disposed elongated openings or slots 115 into which the suitably formed cutters 105, are allowed to enter, in a manner clearly indicated in Figs. 4 and 9 of the drawings. In order to further prevent the sheet-board from saggingI between the compressor-,rolls 'or cylinders, and to be properly fed and guided from one set of rolls or cylinders, to the next set of rolls or cylinders, a

vplurality of fingers- 116 and 117 supportedupon the said bars 101 and rods 118 and narrow belts 119 are also used, power being obtained from a spur-gear 120` which is keyed' upon the intermediate shaft 62, mounted in adjustable bearings 121,I -and said spur-gear being engaged by an intermediate pinion 122 which is mounted upon a stud-shaft 123 rotatably supported in a bracket 124 suitably aflixed to an upright or standard 16. The said pinion meshes with a similar intermediate pinion 125 which is mounted upon a stud-shaft 126 and said pinion 125 meshes with another pinion 127 keyed upon a rotary shaft 128, said shafts 126 and 128 being suitably supported in bearing-portions with which the standard or upright 16 is provided. The previouslymentioned narrow belts 119 are driven from flanged pulleys 129 which are suitably fastened to said rotary shaft 128. Upon a stationary member or element 130 a fixed shaft 131 is supported, upon which are loosely and rotatably mounted a series of iianged pulleys 132 which correspond in number to the narrow belts 119 and` serve to support and properly guide the said belts 119, as will be clearly evident.v Suspended from said shaft 131 are arms 133 between the free end-portions of which is loosely and 4rotatably mounted a tension pulley or roller 134 which is in rolling contact with the lower portions of said belts 119, and tends to at all times maintain the saidibelts under tension. y

As shown, the delivery end of the apparatus or machine is provided with a number of guidepiilleys, as 135, 136, 137 and 1.38, and flanged pulleys, as 139 and 140, the said pulleys being also provided with narrow belts 141, 142 and 143. The said flanged pulley 136 is keyed to a revolving shaft 144 which is mounted in 1i.earin.gblocks 145, as clearly illustrated in Figs. 4, 10 and 13, said bearing-blocks being suitably supported in a suitably formed radial frame 146. Upon one end of said shaft 144 is secured a pinion 147 which meshes with an intermediate gear 148, said gear revolving freely upon a studpin 149 screwed into the end 150 of a swinging yoke 151, said. yoke being loosely mounted by means of the part 153 upon the cylinder-shaft 41, and being also provided with a. slot-ted portion, 151?, which is related concentrically to the said shaft 41, substantially as shown in Fig. 1 3 of the drawings. The previously-mentioned gear 148 engages a gear 154 which is loosely mounted upon said shaft 41, and in mesh with said gear 154 is y an idler-gear, as loosely mounted upon a pin 156 extending from the main frame 15 of the apparatus. said idler-gear in turn engaging a gear 157 which suitalily secured upon the intermediate shaft 63. the purpose of the system or arrangemei'it of gearing being to produce the rotary motion of the shaft 144, so as to properly operate the belts 141- and 142. i l The principal object of the previouslymentioned slotted portion 153, connected with the yoke 4151,is to allow for larger or smaller pinions 147 to be placed upon the shaftl44,

and to lproperly make,the adjustments of' the gears after they" have been set, a bolt 158 entering the said slot 152 and being screwed into a screw-threaded'hole in the side ofthe radial frame 146 and clamped in a stationary position. Motion is transmitted by means of thev fiar- `row belts 141 to the flanged pulleys 135 which are 'loosely supported upon a shaft 80 upon stationary shafts 164 and 165 which are supported in upward projections 166 and 167 formed upon suitably constructed slide-bearings 168 and 169 which in turn are. secured to the main frame 15. A pinion 173 which 'is freely mounted upon a stud-pin 174, also srcured to the said main frame 15, meshes with the spur-gear l64, which is secured upon the cylinder-shaft 41, as clearly shown in -Figs. 2 and 6 ofthe drawings, and to the said shaft 171 is keyed, or otherwise Secured, a pinion 172.'

To the right of the shaft 171 is fixed a spur-gear 182 which is in mesh with a gear 175 suitably secured by being keyed to a cam-shaft 176 which is mounted in standbearings, as 178, suitably bolted to the floor. The said gi fir 175 also meshes with an intermediate pinion 179 which revolves freely upon a stud-pin 180l suitably secured to an arm 181, and which arni 181 is loosely supported upon the said cam-shaft 176. The said pinion 179 also engages with a pinion 182 which is keyed to the shaft 170 mounted, as has been stated, in the bearings 168. A suitable link which is fulcrumed `upon said shaft 170, and is connectedto the stud pin 180 and the arm .181, serves to hold the said pinion 179 in mesh with-the pinion 182 and the cam-gear 175.` Through this arrangement of transmission gearing, motion is transmitted to the flanged pulleys 139 and 140 and to the narrow belts 142 and 143, for the purpose of feeding and guiding the material away from the apparatus or machine, after it has been cut off by means of a suitable cutting-off mechanism. Qne form of such cutting-oill mechanism which it is preferred to apply with the present form of apparatus or machine. consists essentially of an endless steel band-knife 183 which `:is supported 'upon flanged pulleys 184 and 185, suitably secured to stud-shafts 186 and 187 which are mounted'in suitably disposed bearings 188 and 189, connected with reciprocating slides 190and 191. The said reciprocating slides are suitably supported upon vertical slides 192 land 193 which are suitably mounted'in the standardbearings 194 and, 195 which are firmly sel10 cured to the floor. Rectilinear movement of the previously-mentioned band-knife 183' is obtained'from a driven pulley 196 and a suitable belt 197, connected to a pulley upon the counter-shaft 43, as will be evident from an. inspection of Fig.`1l'of the drawings, said -pulley 196 being keyed to a shaft 198 which is mounted in the bearing-portions of al bracket l199, suitablyfastened to a standard 195 and a bearing formed in the previously-mentioned radial j frame 145, `substantially as shown in Figs. 2,10 and 11 of thev drawings. Suitably mounted uponsaid shaft 198 is a pinion 200 which *engages a swinging intermediate gear 201 25 fixed to a. swinging'shaft 202 mounted. in

the bearing-por-tions-of a-,system-of suitably i. arranged links 203, 204,205 and 206.` yUpon its opposite end-portion, thesaid swinging shaft 202 is-provided with a fixed pinion 207 which meshes with a pinion208 secured'l 40 knife 183 from a. b'evel-gear.21`1"which isy keyed l to the saidvv shaft y 209 and .meshes with a bevel gear 212 -whieh'is keyedto' the stub-'shaft 187. The reciproeatorymotion of the said slide 191, see lF, ig.-8 of ,the` drawings, is produced bygme'ans ofa spur-.gear

'213 which is fixed to the end 42A ofthe compressor-roll or cylinder-shaftj41, said spurgear 213engaging with a gear 214'fwhi'ch is keyed *to a short stud-shaft` 215 suitably' mounted inbearing-brackets 216 which are secured to the lmainfra'mel and the upl rights or standards 16. The outer: end of' the said shaft '215 is provided with-fa grooved arm 217, through which is fastened '55' a suitable Ibolt 21,8, withiwhich is connected a turnbuckle or connecting element, as219, j

. which is providedwithright and left screwthreaded eye-bolts 220'and 221,' for the purpose of mutual adjustment, the left screwthreaded eye-boltbei'ng secured to the reciprocating slide 191'by means of a pin 222, or other suitable .fastening means. Through the arrangement and contrivance of these various members, the slide is operated back and forth,'with the aid ofthe stud 215 serv ing as a crank-shaft which may besuitably adjusted to various strokes, as may be neces- A similar arrangementof 'turnbuckle, and gear 213, and other interconnecting parts, is also provided upon Pthe opposite side of the apparatus or machine, operating simultaneously and in unison with the various other devices and parts herein-above described. j

The previously-mentioned vertical'slides 192 and 193, which carry the said reciprocatory slides 190 and 191, carry suitably'disposed anti-friction rollers 223 and 224, said rollers engaging with the grooves 225 and 226 of suitable cams, as 227 -and 228, suitably secured to the outer end of the camshaft 176, `as clearly shown. and whereby the vertical movement, asvwill be clearly evident, is transmittedv to the band-knife. To relieve the pressure of the said antifriction rolls and the said cams, counterweights-229 are provided, said weights beging hung inlevers 230 from members 231 which are adjusted in either direction and are adapted to be clamped in fixed relation,

after adjustment, as will. be evident. The

said levers 2130 are. pivoted upon pins 232, extending 'from bosses upon the standards v'194 and 195, and to the ends 233 of said levers 230 are pins'234 suitably secured to the saidy vertical slides. Thus, it` will be evident, that as the said slides are in motion,

the heavy strains are counteracted andremoved from the cams by the said counterweights. A suitable `brace-bar 235 is also suitably fastened to projections 236 and 237 upon said ,slides 192 and 193, said bracebar being provided with suitable bandknife guides 238 and 239 which prevent the wobbling of the knife when the latter has been properly set.

The bearing 188 which is mounted upon the reciprocating slide 190, see Figs. 2 and 8, is'lcapable of lengthwise adjustment by means of adjusting screws 240 which are 'threaded 'into brackets 241, suitably bolted to said'slide. By means of these adjust- Inents,.lthe said flanged pulley 184 can also l'be adjusted and set in its proper relation to the band-knife, so as to tighten the latter.

`From the foregoing description it will be seen that while the band-knife has a'rectilinear motion laterally across the machine, in front of the belt of the downwardly moving cork-material, the movements of the reciprocatory slides 190' and 191 and thevertically movable slides, conjunction with the cams 227 and 228, will also `produce a motion of the band-knife 183, 'as a whole, in the path ofan" ellipse. Iny this manner, the lower run of the laterally moving endless band-.knifecuts into and through the cork-material as the latter is traveling downwardly, since the forward. motion of .continues without interruption.

the band-knife is contemporaneous With its downward travel and that of the Vstrip or j belt of cork-material which it severs. Thus,

the cork-material is. being intermittently clean cut into the desired length, the cutting portion of theband-knife moving. With the material, and immediately receding. and traveling upward ,apart from the succeed! ing portion oi' the strip or belt Aof corkmaterial, so that the travel of the latter For occasionally sharpening the said band-knife, emery Wheels 242 and 24.3 are provided, which are operated from a suitable belt, as 245 passingover a sheave-pulley 244, keyed to the shaft 196, said belt passing also over sheave-pulleys 246 and 247 and a take-up sheave-pulley 248. The said pulley 246 is fixed to a stud 249 which isloosely supported upon a slide 253, as clearly shown in Figs. 4 and 10 ofthe drawings, said slide beingadjustably mounted upon the radial I frame 146. The emery Wheel 243 is secured npon'a pin 251 which isloosely supported upon a slide 252, slidably arranged in suitable grooves formed in a bracket 253 which is bolted to the upright orrfstandard 16. The means -for adjusting the said emery Wheel consists of a screw-threaded eye-bolt 254,

one end of which is astened to said slide 252. The said boltv is provided with a Wheel-like nut, as 255, the threaded portion of which corresponds to the threaded shank of the eye-bolt 254, and is heldin its opera.- tive relation'between the ends oit' a forkshaped member 256 which is suitably fixed vto the bracket 253. The sheave-pulleys 246 and 247 are fixed to the pin-shafts 249 and 251, and the said take-up sheave-pulley 24S is loosely mounted upon a stud 257 adjustably arranged in a slottedportion 258 with which the said radial frame 146 is provided.

`hen the said band-knife is to be sharpcned, the emcry-Wheels are brought into grinding contact with the said knife, the take-up sheave-pulley 248 beingl properly set, thus taking in the slack of the said belt 245, and from the driven sl'ieave-pulley 244, the said emery-ivheels are set in motion, as will be clearly evident from an inspection of Fig. 13 of the drawings. It ivill be understood that, during this sharpening operation, the reciprocatory slides 190 and 191 and the yertical slides 192 and 193 are put out of motion, and that only the said bandknife and the emery wheels are set in mo- 'i tionv during this grinding operation.

the said bar 262 being secured to'suspended varms 264 which are supported from the said ing in correspondingly screw-threaded parts 268 and 269 of the radial frame 146, are also provided, for the purpose of suitably ad justing the bearing-blocks 160 and 146 when.

necessary, suitable holes or open parts, as 270, being also provided for permitting the placing of the said members in position, as will be clearly evident.

From an inspection of Fig. 4 it Will be seen, that a round bar 272, which has a hand-wheel271 iXed thereto, is provided, the one endportion of said barv 'being loosely mounted upon the adjustablebearing 168, and the other end-portion at said bar being screw-threaded and e zgaging a nut-bracket 27 3 which is suitably secured to the main frame 1.5.

-A suitably constructed belt-shifter 274, which is provided with `a handle 275, is mounted in a bracket 276 which in turn is secured to the bracket 199, as shown, and the operation ofivhich will be clearly understood froman inspection of Fig. 2 of the drawings. v

Means is also provided for mounting. layers of paper upon-the surfaces .of the composition sheetfboard, it desired, and as clearly shown in Fig. 1, the same consisting in an arrangement ot' paperfrolls, as 277 and 278 which are suitably mounted in brackets. 279 and 280, supported, respectively, upon the said uprights or standards 16 and upon nor do I confine myself to the exact details of the construction of the said parts, as illustrated in the accompanying drawings.
